Moving disks from Ultra 1 into 220R

Howdy,

We have an Ultra 1 providing cyrus email services and it
is very overdue for migration to another server. However our
migration should wait until around Christmas, so I'm considering
a switch of hardware with the same disks and OS.

We are running Solaris 6 on the Ultra 1. There are 2 external disk arrays
connected
via SBUS SCSI cards.

The concept is to add one PCI SCSI card to the 220R
(and make use of existing external SCSI connector),
move the internal disks of the Ultra 1 into the 220R,
connect the 2 external arrays and it should just work.

It is running some software mirrored partitions if that can matter.

I've done this before with a single disk in Linux moving
from Ultra 1 to Ultra 60 and it worked well.

Is there anything I am not considering in this approach?

One thing I wondered about was how to identify the controller
number so that our meta device and vfstab are correct.
